| 摘 要： | 查册桥矿区位于江南过渡带，包括牛头高家金矿床、程檀金矿床、路源金矿点和东边金矿化点、杨梅尖金矿点.其中牛头高家金矿是安徽省首次发现的具一定规模的红土型金矿.研究区主体位于东至断裂与高坦断裂带交汇处及其两侧，三岗尖-杨美桥背斜核部及北翼.区内存在多个重要的赋矿层位，主要包括南华系休宁组、南沱组，震旦系蓝田组，寒武系黄柏岭组、杨柳岗组，奥陶系仑山组、东至组.高坦断裂带、兰程畈断裂带、奥陶系/志留系间的推覆-滑覆断层界面均是重要的控岩控矿构造，区内岩浆岩主要受其控制，物化探异常也主要沿其分布.通过对矿床地质特征总结，并结合前人研究成果，对找矿潜力进行分析，认为区内具有寻找低温热液型-叠改型、层控夕卡岩型、岩浆热液脉型金、铜、钨、钼、银、铅锌等矿化的潜力.

| Abstract: | The Zhaceqiao orefield, located in Jiangnan transitional zone, includes the Niutougaojia gold deposit, Chengtan gold deposit, Luyuan gold occurrence, Dongbian gold mineralization spot and Yangmeijian gold occurrence, among which the Niutougaojia gold deposit is of a sizable laterite type first discovered in Anhui Province. The study area is mainly situated in the junction of Dongzhi fault and Gaotan fault zone, and also the core and north wing of Sangangjian-Yangmeiqiao anticline. There are several important ore-bearing strata in the area, mainly including the Nanhua Xiuning and Nantuo formations, Sinian Lantian Formation, Cambrian Huangbailing and Yangliugang formations, and Ordovician Lunshan and Dongzhi formations. As the Gaotan fault zone, Lanchengfan fault zone and nappe-gliding nappe fault plane between Ordovician and Silurian are all important rock- and ore-controlling structures, the magmatic rocks are mainly controlled by them and geophysical and geochemical anomalies are distributed along them as well. By summarizing the geological characteristics of deposit and combining with previous research results, it is concluded that the area has the prospecting potential of mineralization such as epithermal-superimposed reformed type, stratabound skarn type, and magmatic hydrothermal vein type of Au, Cu, W, Mo, Ag and Pb-Zn in the study area. |
